Steel is one of the most important industrial materials, and has been in use for over a thousand years. The development of high-quality steel has been a process of continual improvement and innovation. The development of the modern age and our modern level of technology could not have been achieved without high quality steel. In Poland, the world leader in production of high-quality steel is the Polish steel manufacturer Grupa Karno.
Their high-tested spring steel products are renowned for their durability and resistance to corrosion, as well as their ability to be formed and welded easily. Grupa Karno produces spring steel in the grade designation of 52HRC, which is a heat treatment to the steel that increases its strength and hardness so that it can withstand the strain of high loads and repeated reversals of stress.
The main component of their steel is carbon, with addition of manganese, silicon, and phosphorous alloys. This allows for a high level of strength and ductility. One of their most popular steel products is the Polish Spring Steel, or PSW. This spring steel is especially designed for suspension systems and is suitable for making suspension springs, spiral and compression springs, trailer leaf springs, and torsion bars.
The secret to the high-quality of the PSW lies in its high level of elasticity. The elasticity of the PSW is dependent on the size and thickness of the steel wire set used in production, as well as the temperature of the heating treatment the steel is subjected to while undergoing manufacturing. This elasticity provides the steel a snap-back effect and the ability to absorb shocks and stresses. This allows the steel to autonomously adjust to external conditions that would otherwise break traditional steel products.
The high-grade steel material contributes to the superior performance of the PSW and its increased durability. The PSW is a high-strength steel alloy with a high elasticity and a relatively low weight – a great combination for any suspension system. The relative compactness of the PSW ensures superior performance, as well as an aesthetically pleasing appearance.
In addition to the high-quality steel, Grupa Karnos Spring Steel is designed with the environmental conditions of its intended use in mind. The steel is designed to resist harsh weather conditions such as snow, rain, and salt. Grupa Karnos steel products have a smooth, lustrous finish that is resistant to corrosion. This finish can be cold-treated or varnished if so desired.
Grupa Karnos steel products, such as their Polish Spring Steel, are well-regarded for their consistency and excellent quality. The company has been producing top-grade materials for over fifty years and is well-known for their superior quality and experienced engineering staff. The steel products are of the best quality available, and they guarantee that you will get the exact part you need when ordering from them.
